Technical Abstract:
Epoxidized soybean oil (ESO) has recently been reacted with diamine compounds to produce new polymers which are potential to be utilized in many engineering applications. Among these applications, the components utilizing the polymers may be subjected to different loading and temperature conditions. The compressive response of these soybean oil based polymers at the room temperature has been investigated at a variety of rates of loading. However, temperature effects on their compressive properties have not been understood. In this research, we used both split Hopkinson pressure bar (SHPB) and MTS to characterize the ESO polymers at the temperature range from -50 to 100 deg C. Compressive stress-strain curves at various temperatures are experimentally obtained at two different strain rates: 3000 and 0.01 s-1. All three ESO polymers with different amount of compounds exhibit significant temperature effects at both strain rates.
